PAAS vs IAAS
Huab xam yog ib hom kev xam uas muaj peev xwm tsim muaj nyob hauv internet. Feem ntau cov peev txheej no yog nthuav dav thiab pom tau zoo heev thiab lawv tau muab los ua kev pabcuam. Kev suav huab tau tawg mus rau ob peb pawg sib txawv raws li hom kev pabcuam tau muab. PaaS (Platform as a Service) yog qeb / daim ntawv thov ntawm huab xam uas cov chaw muab kev pabcuam xa cov khoos phis tawj lossis cov txheej txheem daws teeb meem rau lawv cov neeg siv khoom hauv Is Taws Nem. IaaS (Infrastructure as a Service) yog qeb ntawm huab xam uas cov peev txheej tseem ceeb muaj raws li kev pabcuam yog cov khoom siv kho vajtse.
PaaS yog dab tsi?
PaaS yog qeb / daim ntawv thov huab cua uas cov chaw muab kev pabcuam xa cov khoos phis tawj (khoom siv kho vajtse thiab software moj khaum) lossis pawg daws teeb meem (lub khoos phis tawj subsystem xav tau los khiav software). Qhov no ua rau nws ua tau rau cov neeg siv khoom siv rau kev siv daim ntawv thov yam tsis tas yuav yuav thiab tswj cov software tsim nyog thiab kho vajtse yuav tsum tau ua. Lub luag haujlwm ntawm kev tswj xyuas cov khoom siv tsim nyog, kev ua haujlwm, kev pabcuam pabcuam thiab cov ntaub ntawv khaws cia yog lub luag haujlwm ntawm tus muab kev pabcuam. Cov neeg siv PaaS tuaj yeem siv lub platform xa los tsim thiab thaum kawg xa cov ntawv thov web thiab cov kev pabcuam. PaaS cov kev pabcuam feem ntau muab cov txheej txheem ua tiav rau kev tsim, tsim, sim thiab siv cov ntawv thov rau kev sib koom tes hauv pab pawg, kev pabcuam hauv web thiab kev sib koom ua ke ntawm cov ntaub ntawv, kev tswj hwm thiab kev tswj hwm ntawm software. Tag nrho cov chaw no feem ntau muaj nyob rau hauv ib qho kev sib koom ua ke kev loj hlob ib puag ncig ua rau nws yooj yim heev rau cov neeg tsim khoom lossis cov neeg siv. Plaub hom nrov PaaS yog Add-on, Sawv ib leeg, xa khoom nkaus xwb thiab qhib platform PaaS.
IaaS yog dab tsi?
IaaS, qee zaum paub tias Hardware-as-a-Service (HaaS), xa cov khoom siv uas xav tau los ua haujlwm, khaws cia, kho vajtse thiab cov khoom sib txuas (xws li servers) rau lawv cov neeg siv khoom, hauv internet. Hauv lwm lo lus, IaaS cuam tshuam nrog kev muab (hauv virtual, ntawm qhov xav tau) suav cov peev txheej xws li servers, cia thiab lwm yam qis n / w thiab h / w Cheebtsam. Nws yog tib lub luag haujlwm ntawm tus neeg muab kev pabcuam hauv tsev, khiav thiab tswj txhua yam khoom siv kho vajtse. Cov neeg siv khoom yuav them rau ib qho kev siv ib zaug raws li cov qauv siv hluav taws xob suav sau nqi yam tsis tas yuav yuav cov peev txheej tsim nyog. Tus neeg siv yuav tau txais kev xav ntawm kev tau txais kev pabcuam network / server hauv xoom lub sijhawm thiab qhov chaw. Cov chaw muab kev lag luam nrov IaaS yog GoGrid thiab Amazon's EC2.
PaaS thiab IaaS txawv li cas?
Txawm tias, PaaS thiab IaaS yog ob daim ntawv thov / pawg ntawm huab xam, lawv muaj lawv qhov sib txawv tseem ceeb. PaaS yog qeb ntawm huab xam nyob rau hauv uas cov chaw muab kev pab xa ib lub computer platform los yog ib tug daws teeb meem, thaum IaaS tsom rua kev xa cov computer infrastructure xws li hardware resources muaj nyob rau hauv internet. Qhov sib txawv tseem ceeb ntawm ob qhov kev pabcuam no tuaj yeem txheeb xyuas los ntawm hom neeg siv khoom. PaaS feem ntau yog siv los ntawm cov neeg tsim daim ntawv thov, thaum IaaS yog siv los ntawm cov kws tsim qauv hauv network. Hauv lwm lo lus, PaaS muab cov txheej txheem los tsim cov ntawv thov thaum IaaS tsuas yog muab cov txheej txheem tsim nyog los khiav cov cai tsim los ntawm cov neeg tsim daim ntawv thov. Yog li, IaaS muab los ntawm lawv tus kheej tej zaum yuav tsis muaj txiaj ntsig yog tias tsis muaj PaaS uas tsim nyog tau khiav saum nws. PaaS tuaj yeem xav tias yog ib txheej ntxiv ntawm abstraction saum IaaS. Yog tias koj twb muaj cov cai ua haujlwm raws li lub pob ces ib qho IaaS yog qhov tsim nyog dua, thaum yog tias koj tsis muaj cov kev daws teeb meem software hauv qhov chaw (lossis cov kev daws teeb meem tam sim no kim dhau) thiab koj xav tsim cov kev daws teeb meem los ntawm kos, sau npe. mus rau PaaS yog txoj kev mus.
